To succeed when applying for this job at Scorpion Bite Security and potentially many job vacancies in Zimbabwe, the following will be crucial:

1. Experience above all - In my experience, more than qualifications, security jobs value frontline work. Ensure your CV brings out practical experiences, scenarios that tested your mettle, and how you resolved them.

2. Show don’t tell - These types of jobs in Zimbabwe are not looking for verbose individuals, they want action-oriented people. Make sure your CV demonstrates results you’ve achieved, instead of merely listing your responsibilities.

3. Professional Training - Often vacancies in Zim ask for “relevant qualifications”. What it means, largely, is the professional training you’ve undergone. Any degree or high school diploma may not hold as much weightage as a certified course from recognised security agencies.

4. Multitude of ways to apply - Notice the different application methods provided - WhatsApp and phone call. While WhatsApp might lend ease, a call could provide immediate interaction where you can leave an impression. Use your judgement on which to leverage.

5. Mystery Salary - Interestingly, the remuneration is only revealed to successful candidates, which could potentially result in a wide salary range expectation from applicants. It's hoped that they carry a firm and well-researched figure in mind during the negotiation process.

When it comes to standing out among vacancies in Zimbabwe, here’s what I recommend:

1. Being proactive - What I have noticed overtime is that, employers appreciate proactive candidates. Call them up and follow-up. This sense of urgency will reflect positively on you.

2. Personal connections - Networking plays a key role in employment opportunities in Zimbabwe. Use your contacts to get introduced, if possible.

3. Voluntary work - If there’s a lack of actionable experience, express willingness for unpaid work. It blindsides the competition and shows your mettle.

And here’s what most novice applicants might miss:

1. Application Deadline - Note the deadline of 29 January. Many disregard this and miss out, believing the process is flexible. It's a simple filter for employers.

2. Communication Medium - WhatsApp is an informal mode of communication. While for jobs in ZW it might be normal, do remember to maintain text etiquettes and professionalism. Slang or informal language is a no-no.

3. Scope of Work - One must realise that “Job Related” duties could mean anything. Novice applicants fail to ask about this, determining the nature of tasks only once on roll. They could end up in a job with duties not suited to their abilities.

Remember this is mostly applicable for security job offers in Zimbabwe and might differ for ngo jobs in Zimbabwe or for those found through recruitment agencies in Zimbabwe. Happy job hunting!
